LIGHTING UNIT AND DISPLAY DEVICE WITH THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a lighting unit capable of providing uniformity of brightness in a display surface without requiring any complicated process even when a distance between a point light source and a light-receiving surface of a light guide plate is short.SOLUTION: The lighting unit includes: a light guide plate 1; the point light source 3 for illuminating at least one side surface of the light guide plate 1; and an anisotropic light diffuser 8, provided between the light guide plate 1 and the point light source 3, for diffusing light emitted from the point light source 3. The anisotropic light diffuser has anisotropy by which a degree of diffusion differs depending on directions. The anisotropic light diffuser 8 is an anisotropic light diffusion sheet with a particulate dispersion phase 8e included in an anisotropic light diffusion layer 8b thereof.
